ABSTRACT:
The present invention provides a yarn traversing device for traversing a yarn by reciprocating first and second yarn guides respectively along first and second helical cam grooves, comprising a helical cam roller provided with the first and second helical cam grooves each consisting of a substantially linear active traverse groove and a return traverse groove having two curved reversing sections connected respectively to the opposite ends of the active traverse groove. The first and second yarn guides engage the first and second helical cam grooves, respectively, and are disposed one above the other with respect to the running direction of the yarn.
